Blue Flower

This flower is growing in a place that gets only a few minutes of sunshine each day. It’s such a dark blue that, in the shade, my camera fails to capture it. I’ve been meaning to blip it for several days, but today was the first that I got the timing right.

Can anyone tell me the flower’s name, please?

Edit: TonyG has identified it-  Ajuga reptans, common name bugle.
